IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 204,311, dated May 28,1878; application filed March 2, 1878.

To all whom it may concern:

Be it known that I, ANDREW FRIEDLEY, of Lemont, in the county of Cookand State of Illinois, have invented a new and valuable Improvement inSteam Wash-Boilers; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a top view of the boilerwith the lid removed. Fig. 2 is, a longitudinal vertical section thereofwith the lid in place; and Fig. 3 is a vertical cross-section of thesame without the lid.

This invention has relation to wash-boilers having a rectangular orsquare form; and it consists in the slide-valve box arranged above thefalse bottom or diaphragm of the boiler, as hereinafter described andshown.

In the annexed drawings the letter A designates an ordinary rectangularwash-boiler, having a coppe bottom, and divided by a diaphragm, a, intotwo compartments, the one above the other. At the corners of the vesselare formed conduits B, opening below into the lower compartment, andprovided below the lid with the perforations i, for a purposehereinafter explained. These conduits B are formed by spanning eachcorner of the vessel with a plain vertical partition, m, making equalangles with the side and end walls, and bent backward at the top to meetthe walls of the boiler in the angle, thereby forming aflue, closed atthe top, with the exception of the perforations i, above referred to. Inthis manner, instead of a close right-angular corner in the boiler, Ihave an oblique partition and two obtuse angular corners, so that theboiler -wall is brought nearer the clothes, which are generally massedin the central part by the stirring movements, and the corner-spaces, inwhich the clothes seldom get, are utilized as the steam-fines.

In the diaphragm a, near the side of the boiler, is formed an opening,12, through which soap is admitted into the lower compartment,

having at each side the slideways 0, into which is sashed a rectangularmetallic box, B. This box is open at one end, and closed at the other bymeans of a valve, d. It has upon its lateral edges a flange, e, thatengages the slideways aforesaid. This valve is hinged to the top of thebox B, and swings inward freely, but is prevented from swinging outwardbeyond the vertical position by a stop,

, or other equivalent seat.

The operation is as follows: Warm water and soap are passed into thelower part of the boiler through the opening b. The box B is then placedin position, with its open end against the side of the boiler, therebymaking it a close box, and with an opening, I), in its bottom, in linewith the aperture 12 in the diaphragm a, and the clothes put in theboiler. The water soon boils, and the steam generated presses againstand closes the valve 61, and having no other means of egress, passes upthe conduits B, and escapes into the top of the boiler through theapertures i on top of the clothes. The boiler having a tight lid, D,steam is confined therein, and the clothes are thoroughly steamed.

The valve-box is provided with a bail, g, r

by means of which it is readily detachable from the boiler, for thepurpose of pouring out the water, when dirty or it may be drawn off bymeans of a suit-able stop-cock.

What I claim as new, and desire to secure by Letters Patent, is-

In a wash-boiler having the diaphragm a, dividing it into twocompartments, the close valve-box B, sliding by its flanges in ways uponsaid diaphragm, and having the inwardly-swinging valve d at its inwardend, said box and valve being entirely above the diaphragm anddetachable therefrom, as specilied.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ANDREW FRIEDLEY.
